Indian telecom subscriber base is now maturing with increasing usage of next generation telecom services (NGTS). Consumers now look for many services other than voice or short messaging services. The reports released by Telecom Regulatory Authority of India (TRAI), reveals that contribution of data based services in average revenue per user (ARPU) of all the operators is increasing. This paper aims to study the influence of two factors namely switching cost and product/services complexity in adoption of NGTS. Primary data was collected through survey and target respondents were from Delhi/ NCR and Agra city. Analysis of primary data using z test reveals that switching cost and product/ service complexity has negative influence on adoption of NGTS
